Abstract
In frequency-domain Superconducting Quantum Interference Device (SQUID) multiplexing for Transition Edge Sensor (TES) readout, a magnetic field summation method utilizing multi-input SQUIDs has a fundamental merit of small degradation of signal-to-noise ratio. Independent wiring without common impedance avoids the cross talk current, and the current induced by magnetic coupling between the input coils is suppressed by the direct feedback at the summing point. A multi-input SQUID which has 8 input coils has been fabricated and requirements for Flux Locked Loop (FLL) circuits are summarized.
